Using Data

Using data analysis and comparative analysis, the distribution of Coalbed methane (CBM) gas content in southern Junggar were analyzed on the basis of the southern Junggar Basin coalfield geological data, and the main controlling factors of CBM accumulation were studied. The results show that, Gas content ranges from 2cm3/g to 15cm3/g, which overall is highest in central and eastern and becomes progressively smaller in trend of westward. The study area has many characteristics, such as Multi-seam, large coal seam thickness, mainly Fine-grained clastic rock, which is conducive to the enrichment of the CBM. Study area belongs to confined aquifer of low water-richness and receives the supply of atmospheric precipitation and river. In the coal seams within a certain depth formed Runoff water and the CBM diffusion pattern of desorption - diffusion - transport - water soluble gas runoff, which are not conducive to the enrichment of the CBM.

Jixi BasinHegang Basin and Boli basin are major coal mining areas of the Daqing Exploration Area. They are rich in coal resources. In this paper, through analyzing the main controlling factors of the enrichment and reservoiring of the CBM, and the analogy of geological conditions between basins in studying area and other basins, the coalbed methane exploration and development is very successful. Basing on this, the article chooses Fuxin basin and Black Warrior basin as contrast basins to predict the resource by analogy, as the two basins have the similar geological conditions with the basins in studying area. The results show that Jixi basin has the highest total CBM resource, which is as much as 1672.07×108m3. And Hegang basin has the highest score of the potential enrichment of resource, so these two are preferred profitable exploration basins.

Based on the analysis of the relationships between the conditions of structures, sedimentations, source rocks, cap rocks, faults, oil and gas migration passages and traps and hydrocarbon accumulation, the controlling factors of hydrocarbon accumulation and distribution was studied in Talaha-changjiaweizi area. It is held that the source rocks control the hydrocarbon vertical distribution, the drainage capabilities control the hydrocarbon plane distribution, fracture belts control the hydrocarbon accumulation of Talaha syncline, underwater distributary channel is a favorable accumulation environment and reservoir physical properties control the oil and water distributions. Therefore, it is concluded that source rocks, fracture belts, sedimentary microfacies and reservoir physical properties are the main controlling factors of hydrocarbon accumulation and distribution in Talaha-changjiaweizi area.
